From a comment on Cliffski's blog:

The blog post was talking about overcomplication in games like Hearts of Iron, games which push micromanagement to a level that is totally ludicrous.

There are a lot of guys out there who WANT to have to micromanage things like tank repair down to the rivet.
They’re called grognards. There are fewer and fewer of them every year, I think, because tabletop wargaming of the old rivetcounting style is a dying hobby. But they’re out there. I’ve seen them.
There is a reason the HOI guys make HOI. They wouldn’t do it if they didn’t like it themselves. They wouldn’t do it if people didn’t buy it.
The popcap market is huge but unbelievably saturated. The rivetcounting market is a small niche market but is underserved. People in that market buy every title that comes out, and will pay $30 or so for them.
The FPS analogy is ARMA II vs COD. COD games will always serve a larger market, but that means that the market is dominated by big fish. Milsim games don’t appeal to so many people but the competition is much lower.

In my opinion, games need to be deep at the same time that they're accessible.  But there are people who enjoy the crazy complexity of HOI.  They were the people who played the TOTALLY ABSURD tabletop WWII wargames that required two teams of twelve players and took 1200 hours to complete.  That sort of person.

They are out there.
